The Intel service layer driver has defined error codes for the specific services, which started from FPGA configuration then RSU (Remote Status Update). Intel service layer driver should define the standard error codes rather than keep adding more error codes for the new services. The standard error codes will be used by all the clients of Intel service layer driver. Replace FPGA and RSU specific error codes with Intel service layer’s Common error codes.

由 Luis Chamberlain 提交于
Christoph's patch removed two unsused exported symbols, however, one symbol is used by the firmware_loader itself. If CONFIG_FW_LOADER=m so the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail the build at mostpost. ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined! This happens because the variable fw_fallback_config is built into the kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant access to the firmware loader module by exporting it.

Reorder include paths to ensure that runqslower sources are picking up vmlinux.h, generated by runqslower's own Makefile. When runqslower is built from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it might pick up not-yet-complete vmlinux.h, generated by selftests Makefile, which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT) goes first and rely on runqslower's Makefile own dependency chain to ensure vmlinux.h is properly completed before source code relying on it is compiled.

In the prog cmd, the "-d" option turns on the verifier log. This is missed in the "struct_ops" cmd and this patch fixes it.

This adds a new selftest that tests the ability to attach an freplace program to a program type that relies on the expected_attach_type of the target program to pass verification.
